Application filed May 28.1913, Seria1N0.770,340.

To all 10 mm if m (13 camera lie it known that I, ViLLiAM S. GRAHAM, acitizen of the United States, residing at Canton, in the county ofFulton, in the S ate of Illinois, have invented certain new and usefulImprovements in Riding-Cultivators. of which the following is a speification, re 1'- erence being had to the accompanying draw ings.

This invention relates to riding cult ivators and it has tor one of itsobjects the provision otynew and improved means for angling the wheelsrelative to the line of draft and at the same time shifting theshovel-gang lat.- erally.

Another object, of the invention is the improvement of devices 01' thistype in sundry details hereinafter pointed out.

The means by whi h I have accomplished these objects are illustrated inthe drawings and are hereinafter specifically described.

That which I believe to be new is set. forth in the claims.

In the drawings, Figure 1 is a top or plan View of my improvedcultivator; Fig. 2 is a side View of the machine showing one of theshovel-gangs, with one of the supporting wheels removed for clearness ofillustration: Fig. 3 is a top or plan View of my improved cultivatorwith the shovel-gangs and the parts connected therewith removed, showingthe manner of angling the wheels and shift ing the shovelarch laterally;Fig. 4 is an enlarged detail, being substantially a section on line. 4of Fig. 1; Fig. 5 is substantially a section on line 5 of Fig. 1; andFig. 3 is a front view of the bracket. carried by the seat supportingbars and the anti-friction roller mounted thereon.

Referring to the several figures of the drawings in which correspondingparts are indicated by the same reference characters.- 10-11 indicateaxle members each comprising a horizontal portion upon which isjournaled a supporting wheel 12, a vertical portion and an upperhorizontal portion, said axle members being formed either separately orintegrally with each other, the

*upper horizontal portions of said axle memhers l0ll being journaled inbrackets 13 which are suitably conne ted to trained, H at the rear endsat said bars. The torward ends of said bars are. connected to across-bar 15 upon which a tongue 16 jour naled by means (i a bolt 17.

tending between the brackets 13.

it) indicates a transverse frame-bar secured to the frame-bars 14 bymeans of suit.- able brackets 20.

21 indicates a shovel-arch sw ingingly held in position by means ofsubstantially verti cal bars and diagonal rearwardly-extend ing bars213, the bars 22 being connected at their upper ends to the crossbar 19and the bars 25;) being connected at their upper ends to the brackets13.

2 t--25 indicate shovel-beams pivotally su 'iported at. their forwardends by means of brackets 26 upon the laterallyexteuding horizontal.ends of the shovel-arch 21. 27 indicates plows mounted in any suitablemanner upon said beams 24--25. Q8 indieate toot-rests mounted upon saidbeams.

indicates a transverse frame-bar expivota y mounted relative tobell-crank levers have pivotal lever 45 being secured upon therock-shaft 29 by means of a bracket 46.

47-48 indicate arms fixedly mounted upon the ends of the rock-shaft 29,the lower ends of said arms being connected by means of adjustable links49 to the vertical portions of the axle members 10-11, respectivel Aswill be readily understood, when either lever 3233 is swung forwardrelative to its rack 30--31, the corresponding shovel-beam 2524 israised throu h the medium of the links 36--38 and the chain 37, thespring 40 serving to assist in such raising o eration. It will also beunderstood that w en both shovel-gangs are in lowered position the lever45 may be swung forward relative to its rack 44 turning the rock-shaft29 and with it the brackets 34 and levers 32-33, raising theshovel-beams 24-425 in unison. By such a stroke of the lever 45 the arms47 48 are also swung backward in clockwise direction I in Fig. 2,swingin the axle members 10-11 rearward and shi ing the wheels backwardrelative to the frame as is well understood in the art.

Coming now to the means for shifting the shovel-gangs laterally and forangling the wheels, 50-51 indicate bars secured on opposite sides of thetongue 16 at its rear end. 52 indicates a split collar fixedly mountedupon the upper end of the arch 21, as best shown in Fig. 4, said collarbeing provided at one side with a boss 53 which is journaled in asuitable opening in the rear end of the bar 51, being held in positiontherein by means of a suitable bolt 54 passing through said boss. Itwill be understood that by the means 'ust described the shovel-arch 21is the tongue 16.

55-56 indicate brackets secured upon the under side of the cross-bar 19by means of bolts 57. Asbest shown in Fi 5 the brackets 55-56 are in theform 0 tapered bosses, said bosses having mounted upon them bell-cranklevers 58-59, res ectively, which are held in position upon t e bossesby suitable washers mounted upon the bolts 57. The forwardly-extendinarms of said fi connected to them links 60-61, respectively, the innerends of which links are pivotally mounted upon a pin 62 passing throughsuitable openings in the bars 5051 as best shown in Fig. 4.

63-64 indicate seat-frame bars pivotally connected at their front endsto the outwardly-extending arms of the bell-crank le vers 58-59,respectively.

65 indicates a bracket suitably connected to said seat-frame bars 6364near their rear ends havin revolubly mounted upon it a roller 66 whichis adapted to rest upon the transverse frame-bar 18 of the machine.

768 indicate brackets secured upon the roar of the seat-frame bars63-64, respectively, by means of a bolt 69 extending from one to theother of said bars.

-71 indicate seat bars pivotally mount ed at their forward ends upon thebolt 69 and provided at their rear ends with a seat 72. As best shown inFig. 2 the brackets 67-68 are provided at their rear ends witharc-shaped slots 73 concentric about the bolt 69 whereby the seat-bars70-71 are secured by means of bolts 73 in any desired adjusted positionup and down relative to the seatframe bars 63-64. I

As can be understood from an inspection of Fig. 3, when it is desired toshift the shovel-gangs to one side and to angle the wheels so as tocarry the machine as a whole sidewise in the same direction, this can beaccomplished through the medium of the seat-bar. The act of swinging theseat-bar to the operators right, as illustrated in said figure, servesto swing both of the bell-crank levers 5859 in counterclockwisedirection in Fig. 3, swinging the rear end of the tongue to theoperators left and moving the shovel-arch 21 in the same direction. Uponthis movement of the arch 21 the link 23 on the right-hand side of themachine serves to bring the righthand end of said shovel-arch closer tothe axle member 11, and the link on the left-hand side of the machineserves to force the left-hand end of said shovelarch farther from theaxle member 10. That is to say, not only is the shovel-arch 21 shiftedto the left, but also the left'hand wheel is thrown slightly to the rearrelative to the shovel arch and much more to the rear relative to theline of draft, serving to move the machine as a whole to the left. Asthe seatbar swings toward one side or the other of the machine theroller 66 rolls freely upon the upper face of the frame-bar 18 as willbe readily understood. that the seat-frame bars 63-454 be formed so thattheir front ends stand nori'nally closer together than the distancebetween the rear ends of the bell-crank levers 58 59. Consequently whenthe seat-frame bars .63-64 are connected to said bell-crank levers it isnecessary to spring the forward ends of said bars apart against theresiliency of the bars. The bars 6364 thus serve not only to support theseat and to shift the shovel-arch laterally, but also act to take up alllost motion in the connections of said bell-crank levers and of thelinks G0-61 with the tongue.

By reason of the construction illustrated, space is left at the centerof the machine affording the operator ample opportunity to see thestalks of corn, and also making possible the use of a spreader arch ofany Well-known type if desired.
